@kristofdho I want to use

let

because if not null not works with mutable properties, and you need to use !!

just assign to local variable:

Copy code

val v = mutableV
if (v != null) {
   println(v)
} else {
   println("was null")
}

Easier to undersntand and maintain, especially for complex code
